[Pkg-zsh-devel] Bug#1013434: zsh: case-insensitive completion bug (5.9 regression)

[Vincent Lefevre]

Package: zsh
Version: 5.9-1
Severity: normal
Tags: upstream fixed-upstream
Forwarded: https://www.zsh.org/mla/workers/2022/msg00652.html

Case-insensitive completion is buggy.

A first report: https://www.zsh.org/mla/workers/2022/msg00652.html

I've found the same bug (different testcase):

mkdir test-directory
cd test-directory
touch mpfr-impl.h mpfr-intmax.h
autoload -U compinit
compinit
zstyle ':completion:*' matcher-list '' 'm:{a-zA-Z}={A-Za-z}' 'r:|[._-]=* r:|=*'

Then type

  : m-i

and [Tab] to complete on "m-i". I get:

  : mpfr-iN.h

with the cursor over the period. The character "N" is incorrect.

I've attached Bart Schaefer's patch from

  https://www.zsh.org/mla/workers/2022/msg00652.html

(a.k.a. <https://zsh.org/workers/50325>).
